The sixth game in the VideoGame/ProfessorLayton series, third in the prequel series. It is also, according to WordOfGod, the final game in the series to feature Layton himself; though not the last game overall.

Layton receives a letter from professor Desmond Sycamore, who requests his help in solving a mystery he has stumbled upon: the identity of a young girl who was frozen in ice for millions of years, but is inexplicably still alive. The girl is the key to solving the mysteries of the ancient Azran civilization, and it becomes clear that Layton and his friends aren't the only ones who are interested in doing so...

A first to the series, instead of remaining in a single locale or two, players are tasked to travel around the world to visit other locations connected to the main plot, all of them holding their fair share of puzzles and mysteries to solve the biggest mystery of the Azran Legacy.

----!!This game provides examples of:* AntiquatedLinguistics: Julien. Good heavens. [[GratuitousIambicPentameter It's not just that he speaks in words of old / but, by habit, he speaks in metered verse]]!* AndTheAdventureContinues: The last scene of the game is like this, showing Layton and Luke heading off to another adventure. It's also a {{BookEnds|}} for the series.* AndYourRewardIsClothes: The "dress up" minigame.* AndYourRewardIsInteriorDecorating: Most of the rewards for the [=StreetPass=] treasure hunt sidequest are decoration items for the Bostonius.* AerialCanyonChase: We get one of these early on in the game. Use your puzzle solving skills to shoot down unmanned drones and missiles!* ArcWelding: [[spoiler: Sycamore goes over the fact that the Golden Garden, Ambrosia, and the Nautilus Chamber, respectively uncovered in ''Last Specter'', ''Eternal Diva'' and ''Miracle Mask'', are all examples of Azran civilization. Soon after, another is revealed to be under Lake Kodh.]]* TheAtoner: Sage Sheppard sees helping young people find love as his greatest joy and his means of atoning for his complicity with Hoogland's [[spoiler:human sacrifices to the Dragonlord]].* BatmanGambit: [[spoiler:Descole/Sycamore basically uses this in allowing Layton and crew to travel with him. He knew that Layton would want to solve the puzzle, and used that against him in order to get the key -- to try and keep said key out of Targent's hands. Unfortunately, it doesn't quite work out, as Targent had a mole in the party.]]* BeachEpisode: The island in chapter four.* BookEnds:The last scene after the credits has Layton and Luke driving to St. Mystere, which was the very first scene of ''The Curious Village''.* ButNowIMustGo: ** [[spoiler:Descole doesn't join everyone when the Azran Sanctuary starts to fall apart. He says goodbye to Layton, and is later seen riding off on the Bostonius with Raymond.]]** Emmy pulls this at the very end too after [[spoiler:being revealed as a Targent spy]], mostly because [[DoomedByCanon she wasn't in the original trilogy]] it seems.* CantSeeADamnThing: One of the quests. [[spoiler:The truth is that the Chief is simply BlindWithoutEm.]]* CallBack: All over the place, fittingly so for Layton's (the character, not the series) last game.** [[spoiler:Luke's parents, Clark and Brenda, show up. Clark even helps out!]]** [[spoiler:Layton's parents get in a visit as well, thanks to Sycamore.]]** [[spoiler:Layton fights Descole with a pipe - just like in ''Eternal Diva''.]]** One of the puzzles references the Ambrosia legend from ''Eternal Diva'', even mentioning the kingdom's beloved queen.** Luke's habit of touching fire is brought up twice, once with him hurting himself and another with him resisting.* CallForward: ** [[spoiler:Chelmey and his newly-married wife are seen at the aerodrome, going on their honeymoon together. Awwwww.]]*** [[spoiler:Interestingly enough, Chelmey cannot be interacted with, and is always looking away or distracted with something, in keeping with Layton meeting him for the first time in "The Curious Village"]].** In [[VideoGame/ProfessorLaytonAndTheCuriousVillage Curious Village]], one of Layton's responses to a wrong answer is, "frankly, I'm ashamed". Here, that particular response has returned (albeit, in a harsher tone of voice. Ouch to anyone who manages to invoke that response.)** [[spoiler:Also the ending, where Luke and Layton are shown driving towards the Curious Village]].** One of the sidequests is a collection game where the player finds stated objects for points. You can trade in the points for prizes. Three of the prizes are hotel room tickets -- Curious, Surreal, and Future. The Curious Room shows you a locale that looks vaguely like St. Mystere, and Stachenscarfen speaks to you! The original puzzle music plays as well!** The Surreal Suite shows Folsense, and the Future Suite -- as its name suggests -- is Future London.** [[spoiler:To catch up with Descole, Layton builds a hang-glider out of a fossil and some fabric. Just like in ''VideoGame/ProfessorLaytonAndTheCuriousVillage''.]] And touching the globe as a tool to use (the way Layton did before) will trigger a puzzle.** In one of the final scenes of the game [[spoiler:As Emmy is about to leave she bursts into tears and hugs Layton, just like Luke will eventually do at the end of the following trilogy.]]* ChekhovsGun: [[spoiler:At the Hoogland chapel, a magnet takes away Julien's shovel. At the entrance to the Azran Sanctuary, another one takes away a Targent {{Mook}}'s gun.]]** The [[spoiler:dormis soporis mushrooms]] from Mosinnia. Sycamore uses them to take out a guard.* CloseKnitCommunity: Most of the places visited by Layton and crew on their adventure. San Grio in particular is especially so, given that one of the customs is passing around the "original popono" to other people, to wish them good fortune.* CollapsingLair: [[spoiler:The Azran Sanctuary becomes this once it has fulfilled its purpose.]]* CosmeticAward: The trophies you get for completing the daily puzzles, which are significant objects and places from throughout the series.* CrazyPrepared: Sycamore [[spoiler:especially during the part in Targent's HQ. Sleeping smoke bombs!]]* CuteKitten: Keats reappears in this game. Raymond and Keats are shown to have struck up an adorable friendship in one of the episodes found during your adventures. * DarkerAndEdgier: Feels this way in comparison to the previous games. It helps that there is a ''lot'' more at stake this time.* DramaticUnmask: This one's a staple of the series. [[spoiler:In this case, the reveal that Sycamore is Descole.]]* DrivenToSuicide: Played straight then averted as [[spoiler: Romilda about to be sacrificed, when given a chance to escape, she refuses to run away, nor die on their terms. She was planning on killing herself to spite the townspeople on how stupid the custom sacrifices were, until the heroes discover a [[TakeAThirdOption ThirdOption]] ]]* EmptyPilesOfClothing: Invoked by one of the mysteries, which involves [[spoiler: young girls from the town of Hoogland being sacrificed to calm down a wind deity. Upon being sacrificed, the girls are said to transform into a breeze, leaving all their clothing behind]].* EndlessWinter: Froenborg, seemingly.* EnemyMine: [[spoiler:After Bronev opens the door to the Azran sanctuary, kidnaps Aurora, and has Emmy betray Layton, the latter and Descole team up to stop them. [[TeethClenchedTeamwork Neither of them are happy about it.]]]]* EvenEvilHasStandards: [[spoiler: Macaw may be loyal to Targent, but he decides to quit after deciding killing people is just too much for him. Robin follows soon afterwards.]]* FaceOfAThug: [[spoiler: Old Red is a threatening-looking CanisMajor, but he's a big softy at heart.]]* FanGirl: Hannah of the Groskettes is back.* {{Filler}}: The entirety of chapter 4. It takes up half of the game storywise and consists of five sub-chapters, each with their own side-stories that have nothing to do with the overarching plotline.* FiveManBand: Layton's team over the course of the game.** TheHero: Layton himself, of course.** TheLancer: Luke.** TheBigGuy: Emmy, the strongest, most agile, and generally most physically able member of the team.** TheSmartGuy: Professor Sycamore, whose knowledge is indispensable throughout the journey.** TheChick: Aurora.* FollowYourNose: [[spoiler:Chief Morel. Although he's BlindWithoutEm, he's been able to walk around just fine by following the scent of the local rafflesias and his wife's meals.]]* GhibliHills: Hoogland, a breezy hilly locale visited in chapter four.... * GustyGlade: ...With lots of [[WindTurbinePower windmills]]. The area is apparently prone to tornadoes. The locals don't even seem particularly rattled, despite the destruction they cause.* GlobalAirship: Layton's party travels in one of these -- and it really DOES go worldwide! The antagonists also have one.* GottaCatchThemAll: The quest for the Azran eggs.* GratuitousFrench: One of the [=NPC=]s at San Grio. In the French dub, it becomes GratuitousGerman.* GratuitousIambicPentameter: Julian in particular speaks like he's in a Shakespearean play, even working in a ''Theatre/{{Hamlet}}'' reference at one point.* GratuitousSpanish: The rest of the [=NPC=]s at San Grio.* GuestStarPartyMember: [[spoiler:Descole, surprisingly enough. He even gets to solve puzzles of his own!]]* HeelFaceTurn: [[spoiler: Double subverted by Emmy and played straight by Bronev.]]** [[spoiler: Emmy was never evil, but she did work for Targent all along, and betrayed Layton and Luke. However, she only did so to try and bring Bronev out of his obsession for the Azran legacy, helped stop the Azran golems, and never did anything irredeemably bad, leading Layton and Luke to forgive her (Though she does leave Layton's side, partially out of guilt, Layton makes it clear that she can stay with him as an assistant if she wants).]] ** [[spoiler: After realizing how far he went to uncover the Azrans' secrets, how much it cost him (Namely his wife and sons), how meaningless his quest turned out to be and the danger he unleashed upon the world by releasing the Azran golems, Bronev is devastated. Helped by a speech from Layton, he helps stop the golems by sacrificing his life, though he is revived. Though Layton still considers the Layton couple his parents, he isn't against the idea of meeting Bronev again as an archeologist, maybe even a friend, after he has served his prison sentence.]] * HeroicBSOD: ** [[spoiler:Aurora has one of these once her memories return, and attempts to jump off the top of the Targent tower. It's only through Layton's [[YouAreNotAlone intervention]] that she finds the courage to make her own future.]]** [[spoiler:Layton gets one of these as well, when Bronev threatens his mum and dad. Sycamore snaps him out of it.]]** VillainousBSOD: [[spoiler:Bronev upon realizing that the Azran Legacy would destroy the world rather than improve it, as he and his late wife had hoped. Layton pulls him out of it.]]* HumanPopsicle: Aurora, who survived millions of years of being trapped in a giant ice cube. [[FishOutOfTemporalWater She has a lot of catching up to do after she wakes up]].* HundredPercentCompletion: As always, there are curiosities and bits and pieces to find. Good luck!** The reward for completing all the puzzles is a final Episode, in which [[spoiler:Layton, Luke and Emmy reminisce about their adventures in the game and thank the player for everything]].* ItsAllUpstairsFromHere: As per usual for the series, the confrontation at [[spoiler:Targent's HQ]] is this.* JungleJapes: One of the settings the airship flies to during chapter four is a jungle.* LethalChef: Larisa. Fish smoothies. Snails in trifle! Yikes!* LikeFatherLikeSon: [[spoiler: Layton and Bronev in the credits, both teaching about the Azran - Bronev in prison, Layton in Gressenheller.]]* MacGyvering: Pretty much standard for the series by now. [[spoiler:The Professor constructs a hang-glider out of a fossilized skeleton, fabric, and a few other odds and ends.]]* MoleInCharge: [[spoiler:DI Bloom. Eventually this is puzzled out by Layton, who confronts him.]]* MysticalWaif: [[spoiler:Aurora]]. By sheer act of getting mad, she blows out the antagonist's engines. And then faints.* ObfuscatingStupidity: Layton pulls this early on in the game to get past some mooks.* PointOfNoReturn: [[spoiler: Bronev's office at the top of Targent's HQ.]] The game warns you that you won't be able to travel wherever you want after you pass this point, though. [[spoiler: It's eventually subverted when you beat the game, after which you can exit the last room of the Azran sanctuary, allowing you to travel throughout the world as if you hadn't beaten chapter 5 (Complete with Sycamore, Emmy and Aurora in your party). You can go back to the last room to finish the main quest again, of course.]]* PrecociousCrush: Luke and Aurora. * {{Pun}}: ** A village in the jungle in which the buildings are shaped like mushrooms, is named "Phong Gi". ** Also, the name for the glue snail is "glutinus maxiumus". ** Then there's a mushroom name: "Ommis Nommis". Doubles as a shout out to the internet meme.** Professor Sycamore's jokes, which are lame enough to make people stop laughing.* PungeonMaster: Raymond, of all people! (Much to Sycamore's chagrin.)* RegretfulTraitor: [[spoiler:After Emmy reveals that she's been TheMole the entire time, she expresses regret at having been so.]]** After [[spoiler:she's been forgiven, she resigns as Layton's assistant, feeling ashamed and unworthy to fill such a role anymore.]]* RunningGag: Luke, Emmy, and Layton looking in the mirror.* RetailTherapy: ** Courtesy of Emmy, [[spoiler:Aurora]] gets some of this, complete with a cutscene of them shopping for clothes, and then Emmy prompting Layton and Luke for their opinions. Crosses over with TheMakeover [[spoiler:as it's a means of helping Aurora to create a disguise]]. ** [[spoiler: Luke gets a little of this in the end credits as well, courtesy of his parents. He gets his outfit from Curious Village, to be precise.]]* RobotWar: [[spoiler:This was what brought down the Azran civilization- they built golems that were as intelligent as people, but only treated them as tools, causing them to rebel.]]* SeriesFinale: Double subverted. This isn't the final game in the series, but it is Layton's final game. Crosses over into Zigzagged territory when you consider it's only the 3rd out of 6 games chronologically and thus is technically not the finale.* SequelHook: Subverted; the game ends with Layton and Luke heading off on a new adventure, but it's not actually a ''new'' one- it's ''The Curious Village'', the series' first game.* SceneryGorn: ** Verges on this in Chapter 2, set in the town of Kodh. It's quite a bleak place, really -- seems kind of run down and a bit shabby. ** [[spoiler:The Nest also counts as this.]]* SceneryPorn: The entire game, though some locations like San Grio stand out even more.* ShoutOutToShakespeare: Hoogland has the couple of [[Theatre/RomeoAndJuliet Romilda and Julien.]]* TeethClenchedTeamwork: [[spoiler:Descole and Layton, to stop Bronev. Luke gives Descole all kinds of heck over this, causing Layton to scold him.]]* ThePhoenix: Mosinnia's motif and town mythology is based around this.* ThirstyDesert: Torrido is based in one of these. Has a [[TheWildWest Wild West]] theme and feel to it.* TakesTheBullet: [[spoiler:Descole, for Luke, when one of the laser-shooting statues reactivates.]]* ThatManIsDead: [[spoiler:The spirit of the trope is invoked by Layton in the ending, who learns that his real name is Theodore Bronev. Layton says that Hershel Layton is the only name he needs.]]* ThatRemindsMeOfASong: Once again, some of the puzzles can come completely out of left field. For example, a woman in Hoogland gets angry with you and bluntly asks you to leave... after you complete a puzzle.* TheMole: ** [[spoiler: Emmy. It turns out she had been reporting Layton's progress on discovering the Azran legacies.]]** [[spoiler: Bloom is also exposed as a mole for Targent]], although the previous game made it clear.* ThoseTwoBadGuys: Robin and Macaw. The latter, though not exceptionally bright, is much smarter, calmer and more competent than his partner.* TomatoInTheMirror: [[spoiler:Aurora's a golem.]]* TownWithADarkSecret: Hoogland, of all places. [[spoiler: Young girls are regularly "wed" to a wind deity to calm down the strong winds it can create. And by "wed", we mean sacrificed,]]* TrialAndErrorGameplay: The dress-up puzzles. All of the people you need to help have certain requirements for their outfits, such as its attributes, colors and other things. If you meet all those requirements, however, the person may tell you that a certain piece of clothing isn't quite what they had in mind (albeit with a hint as to what they're thinking about), so you have to switch out the clothes until you get the right combination.* VirginSacrifice: Hoogland's ritual of marrying young women to the Dragonlord to calm the fierce winds that blow through the town is basically this. [[spoiler:Layton later discovers that the "Dragonlord" is actually a malfunctioning Azran WeatherControlMachine, and a local woman has been using an old network of tunnels to sneak the sacrificed girls out of town.]]* WeatherControlMachine: [[spoiler: The source of Hoogland's problems.]]* WhamEpisode: Starting from the end of Chapter 5, the game throws whams at you relentlessly, but four of them are especially big: [[spoiler: Emmy was working as a mole for Targent all along, Descole explains of his shared past with Layton, revealing that he is his ''brother'', that Hershel was actually '''Descole's''' name and that Layton was '''adopted''', and that their father is none other than ''Bronev''.]] '''Holy crap'''.* Unexplained Recovery: [[spoiler: Descole. The final chapters of the game heavily imply that he dies, but he's later revealed to be OK.]]* WhamLine:-->'''Young Professor Layton:''' But [[spoiler: Hershel]], I want to stay with you!* WhatHappenedToTheMouse: At one point in chapter 4 Professor Sycamore casually mentions [[spoiler:that he once had a daughter, but she died several years ago.]] Emmy, like everyone playing the game, is utterly shocked by this. It never gets mentioned again in the plot.** In one of the post-game episodes it's revealed that [[spoiler:Sycamore's wife and daughter died together]], and is implied that Targent was involved somehow, but this major piece of backstory is never touched on again.* WhatMeasureIsANonHuman: [[spoiler:The Azran civilization's downfall was a result of creating a race of golems, and forcing them to do manual labor despite them having emotions, resulting in them rising up and killing them. When they awaken and start to destroy humanity, Layton and company's only means of stopping them results in them falling to earth and breaking them; they show relatively little reaction, although they had no other means of stopping them]].
